Jean Dominique Cassini

Jean Dominique Cassini was a 17th-century French astronomer renowned for his work in studying the planets, moons, and the structure of our solar system. He made significant discoveries, such as identifying the gap in Saturn's rings now called the "Cassini Division." Cassini also helped develop precise astronomical instruments and methods for observing celestial bodies. His contributions greatly advanced our understanding of planetary systems and space observation techniques, laying important groundwork for future astronomy.
